Inflatable Seat

Abstract

An inflatable seat includes a seat part and a backrest part which is connected to the seat part to define an inflation chamber, wherein the backrest part comprises a first layer and a second layer, wherein the second layer includes a first folding line and a second folding line which are connected with each other to form a connecting seam, wherein when the backrest part is inflated, the connecting seam causes the second layer to be deformed to form a concave groove while the first layer forms a protrusion section for supporting a waist of a user.

What is claimed is: 
     
         1 . An inflatable seat assembly, comprising:
 an inflatable seat which comprises a seat part and a backrest part which is connected to said seat part; and   a cover detachably coupled to said inflatable seat.   
     
     
         2 . The inflatable seat assembly, as recited in  claim 1 , wherein said backrest part comprises a first layer and a second layer, wherein said second layer comprises a first folding line and a second folding line which are connected with each other to form a connecting seam, wherein when said backrest part is inflated, said connecting seam causes said second layer to be deformed to form a concave groove while said first layer forms a protrusion section. 
     
     
         3 . The inflatable seat assembly, as recited in  claim 1 , wherein said backrest part is connected to said seat part to define an inflation chamber, wherein said backrest part comprises a first layer and a second layer, wherein said second layer comprises a folding portion which is folded into said inflation chamber, so as to cause said first layer to form a curved surface with a raised peak position for conforming to a back of a user when said backrest part is inflated. 
     
     
         4 . The inflatable seat assembly, as recited in  claim 1 , wherein said backrest part comprises a first effective inflation layer and a second effective inflation layer, wherein each of said first effective inflation layer and said second effective inflation layer is made of inflation brushed cloth and an area difference between said first effective inflation layer and said second effective inflation layer causes said fist effective inflation layer to form a curved surface for conforming to a back of a user when said backrest part is inflated. 
     
     
         5 . The inflatable seat assembly, as recited in  claim 2 , wherein said backrest part is detachably coupled to said seat part. 
     
     
         6 . The inflatable seat assembly, as recited in  claim 2 , wherein said cover comprises a cover body and two armrest portions extended from two sides of said cover body, wherein said inflatable seat is detachably received in said cover body. 
     
     
         7 . The inflatable seat assembly, as recited in  claim 3 , wherein said cover comprises a cover body and two armrest portions extended from two sides of said cover body, wherein said inflatable seat is detachably received in said cover body. 
     
     
         8 . The inflatable seat assembly, as recited in  claim 4 , wherein said cover comprises a cover body and two armrest portions extended from two sides of said cover body, wherein said inflatable seat is detachably received in said cover body. 
     
     
         9 . The inflatable seat assembly, as recited in  claim 5 , wherein said cover comprises a cover body and two armrest portions extended from two sides of said cover body, wherein said inflatable seat is detachably received in said cover body. 
     
     
         10 . The inflatable seat assembly, as recited in  claim 6 , wherein said cover body comprises a seat cover portion and a backrest cover portion connected to said seat cover portion, wherein each of said two armrest portions comprises an outer flexible layer and an inner member which is formed by an air column which is disposed in said outer flexible layer. 
     
     
         11 . The inflatable seat assembly, as recited in  claim 8 , wherein said cover body comprises a seat cover portion and a backrest cover portion connected to said seat cover portion, wherein each of said two armrest portions comprises an outer flexible layer and an inner member which is formed by an air column which is disposed in said outer flexible layer. 
     
     
         12 . The inflatable seat assembly, as recited in  claim 2 , wherein said cover comprises a cover body and two side portions extended from two sides of said cover body to support arms of a user, wherein said inflatable seat is detachably received in said cover body. 
     
     
         13 . The inflatable seat assembly, as recited in  claim 4 , wherein said cover comprises a cover body and two side portions extended from two sides of said cover body to support arms of a user, wherein said inflatable seat is detachably received in said cover body. 
     
     
         14 . The inflatable seat assembly, as recited in  claim 12 , wherein each of said two side portions is inflatable. 
     
     
         15 . The inflatable seat assembly, as recited in  claim 12 , wherein each of said two side portion comprises an outer cover portion and an inner rigid portion disposed in said outer cover portion. 
     
     
         16 . The inflatable seat assembly, as recited in  claim 2 , wherein said cover comprises a cover body and two armrest portions extended from two sides of said cover body, wherein said inflatable seat is detachably received in said cover body, wherein said cover body comprises two end cover portions which are respectively detachably sleeved on end portions of said seat part and said armrest part of said inflatable seat. 
     
     
         17 . The inflatable seat assembly, as recited in  claim 6 , wherein said cover body comprises two fastening straps provided at a bottom of said cover body, wherein said two fastening straps are detachably coupled with each other. 
     
     
         18 . The inflatable seat assembly, as recited in  claim 6 , wherein said cover body comprises two fastening straps provided at a bottom of said seat part, wherein said two fastening straps are detachably coupled with each other. 
     
     
         19 . The inflatable seat assembly, as recited in  claim 10 , wherein said cover comprises a heating element disposed in said seat cover portion.
